SMR drives get a bad rap; they are perfectly usable as long as expectations are set correctly to begin with. - they are NOT FAST, especially for rapid writes, or once they've been written 100% to. - they are TERRIBLE when resilvered. expect 10x resilver times so no raidz1- ever. - may not be...

I find them even unusable and slowing down the whole system when using them as a single disk with NTFS/ext4 on top. Not even useful to store backups on it.

Should be mentioned: every SMR disk performs crappy in RAID environments, not only with ZFS.

Newer "WD Red" use terrible SMR and therefore shouldn't be used with ZFS. Only the "WD Red Pro" and "WD Red Plus" use CMR. Old "WD Red" could use SMR or CMR. Your WD40EFAX uses SMR and therefore will horribly suck at writing once the cache is full. Similar to what you see with QLC SSDs.

...for a Lexar, but go for "pro" level instead of "evo", knowwhutImean? Get a high-rated TBW drive, and stay well away from QVO and especially SMR drives - you want CMR. And put everything on UPS power. Edit: for ZFS you want a SAS HBA in IT mode (actively cooled), try to keep as much as...

...you use a "zpool attach": https://pve.proxmox.com/wiki/ZFS_on_Linux#_zfs_administration And don't cheap out on storage. Enterprise/Datacenter SSDs with power-loss protection are highly recommended when using ZFS. And avoid everything that uses QLC NAND flash or shingled magnetic recording (SMR).

Why would you have plex in a separate VM ? I'm not familiar with container at all so rn i don't really know which one's the better You may not and that's why i'm asking ahah, i'm a complete begginer with no exp at all in that kind of stuff But my plan was using TrueNAS for the easy raid...

...also not great as a VM/LXC storage because of worse IOPS performance. Again, best to use it for cold storage. Make sure to buy CMR HDDs and avoid SMR HDDs. Especially when using CoW like ZFS does. Minecraft runs fine on linux. No idea about Rust and Palworld. But security wise I would use a...

I understand very well everything you tell me. But the goal is not to have a giga setup, I just want a vm that allows you to play games like GTA or RDR2. And storage is only for files, I don't have thousands of them and are all backed up on an external hard drive. So I don't think I need a whole...

...und entsprechend höherem Overhead. So sollte man z.B. am besten keine Consumer SSDs benutzen, erst recht keine QLC SSDs und auch keine SMR HDDs. Wenn man Wert auf seine Daten legt trotzdem die beste Option, da im Gegensatz zu den simpleren Dateisystem auf Datenintegrität geprüft wird. Wenn...

You say that now, but people tend to not respond well when we point out they wasted money on QLC or SMR drives for example. Or how issues could have been avoided. I do try to suggest things that I think improves your setup the long run, based on my experience (on this forum and otherwise). Good...

Man sollte immer SMR (Shingled Magnetic Recording) HDDs vermeiden und stattdessen CMR (Conventional Magnetic Recording) HDDs kaufen. Besonders bei Copy-on-Write Dateisystemen wie ZFS. Am billigsten war es immer wenn man USB-HDDs kauft und diese ausschlachtet um an die SATA HDDs zu kommen. Bei...

Anyone saying that never had to sit through a rebuild/resilver with SMR drives ;) HDDs are never a "better" option for virtualization, as they are an order of magnitude poorer in IOPs. I'd take the cheapest consumer SSDs over HDDs for that use case. QLC SSDs in garbage collection mode still...

Hi. I've been thinking a lot. I came to this conclusion. If I'm wrong please tell me. I am going to buy 2 SSDs with a capacity of 120GB for the operating system using zfs mirror. I will use the four SSDs with a capacity of 400GB disks in RAIDZ 10 for VMs. I will use the four 6TB disks for...

...have to stick with those diska you got. Maybe also add 2 additional SSDs in a mirror as special devices to speed the disks up. You shoulsn't use SMR (shingled magnetic recording) disks. But as long as those consumer disks are CMR it should be fine. At least in a homelab. But not a good idea...

...I was hoping on a 'faster' copy strategy, without putting the redundancy down to z1. This will have to do then.

...und ISO-Share verwenden. Wenn die nur für Backups gedacht ist, wäre auch zeitgesteuertes Ein- und Ausschalten möglich (nur an zur Zeit des Backups). Bei den WD RED musst Du nur überprüfen, ob das CMR oder SMR Modelle sind, falls Du diese im RAID der QNAP nutzen willst. SMR ist für RAID...

...and discussion [3] regarding this feature. Furthermore, since you are using 12TB and 22TB disks, I would like to point out, that this may be SMR disks. SMR disks are known to perform poorly with ZFS [4]. Make sure to verify beforehand, because shrinking a pool is not possible. [1]...

...Aber ZFS hat auch seine Ansprüche. Mehr Overhead daher langsamer und schnellere SSD-Abnutzung, braucht viel RAM fürs Caching, man sollte keine SMR HDDs oder Consumer SSDs nutzen, ECC RAM wenn man sich auf Datenintegrität verlassen will etc. LVM-Thin unterstützt Snapshots und Thin-Provisioning...

Running ZFS with consumer SSDs or SMR HDDs? Whats the peak IO delay on the PVE host? Any passthroughed HDDs that might need to spin up first?
